Well i think i am finally buying a boat

Well everyone who has put there 2cents in i really appreciated it. I decided against the 97 mastercraft 205 because of who owns it and i am worried about the history and dealling with shady people. I came across a 98 mastercraft xstar that appears to be in pristene condition. The owner has sent me something like 30 photos of the boat because he wants me to be 100% of the boat before i drive 13hrs. He also has taken care of the boat which is also sometimes hard to find. From the pictures the xstar looks almost perfect and especially nice since it is a 98. The only thing that isn't the best is the fact that the motor has 800 or so hrs on it. BUT the owner is always doing preventive maintanence to the boat. For example he was telling me that every year he replaces the water pump impeller because he wants to prevent it ever wearing out so it can't cause the motor to over heat. Even though the pump impeller is in great condition he still buys a new one and installs it. So with that kind of maintanence the motor should last a long time as long as i continue doing it. Is there anything i should look for when i go and meet the guy to buy the boat? Am i making a mistake? If the boat is in as good as condition as he is saying and from what i am seeing is 25k to much? Here is the specs on the boat:
